Final answer:
The statement that permeability describes the relative ease with which a material can be magnetized is true. Magnetic permeability indicates a material's ability to support or strengthen an external magnetic field.
Step-by-step explanation:
The term 'permeability' describes the relative ease with which a material can be magnetized, so the statement is true. The magnetic permeability of a substance is a measure of the substance's ability to support or amplify an already existing external magnetic field. Materials like iron, which are ferromagnetic, have high permeability because their magnetic domains align with and amplify an external magnetic field. In mathematical terms, magnetic permeability is denoted by μ, where μ = (1 + χ) μ0. Here, μ0 represents the permeability of free space, which is a constant (approximately 4x10-7 T·m/A) and χ is the magnetic susceptibility.
